Migration service
Migrate to NexCMP with an expert engineer
Moving a live cloud business is mostly planning, testing and a careful cutover. With the NexCMP Source upgrade you get 30 working days of continuous work with an expert engineer, who migrates you from VMware to Apache CloudStack, from WHMCS to NexCMP, or from any other billing panel, at no extra charge.
Included with NexCMP Source only, not with NexCMP Free. VMware, WHMCS, HostBill, Blesta, Paymenter, StackBill, Virtualizor and Apache CloudStack are trademarks of their respective owners. NexCMP is independent and not affiliated with or endorsed by them.
Why migrations stall
Most teams know where they want to be: virtual machines on Apache CloudStack, customers and billing in one self-hosted system. What stops them is the move itself. Virtual machines have to be converted and tested, customer balances and services have to be carried over exactly, and the day billing switches over has to be chosen so nobody is charged twice or not at all.
A migration is also easy to underestimate, because the work is spread over inventory, a target environment, trial runs, several waves of moves and a final cutover. Doing it with an engineer who has done the steps before keeps it a plan with dates instead of a side project.
What we can migrate for you
Pick the one that matches where you are today. Each page explains what moves, the plan week by week, the risks and what we need from you.
VMware to Apache CloudStack
Plan and run the move of virtual machines from VMware vCenter into a CloudStack zone, using the import and conversion features that CloudStack itself provides. Cutover is planned VM by VM.
WHMCS to NexCMP
Read customers, credit balances, services and plans out of WHMCS and rebuild them in NexCMP, then run both systems side by side until you switch billing over. NexCMP is not WHMCS, so the page says plainly what is rebuilt and what is archived.
Any other system or billing panel
HostBill, Blesta, Paymenter, StackBill, Virtualizor or a system of your own: the same method of inventory, export, mapping, dry run and cutover.
Full A-to-Z setup and branded apps
If you would rather have the whole system set up for you, and every app built under your brand, the same 30 working days can be used for that instead.
What is included, and what is not
The service belongs to one edition only.

The migration and expert service is not part of NexCMP Free. It comes only with NexCMP Source. The 30 working days start when you begin the work with the expert; the date is shown on your license page. Thirty working days is about six calendar weeks.
A typical plan, week by week
Typical, adjusted to your case. The first week produces the real plan, with your systems, your constraints and your dates in it.
Week 1 — Inventory and plan
We read what you have: virtual machines, customers, services, plans, payment gateways. Together we decide what moves, what is rebuilt, what is archived, and the order of the waves.
Week 2 — Build the target
The target environment is prepared: the CloudStack zone, or the NexCMP install with your branding, plans and payment channels. Nothing is switched yet.
Week 3 — Pilot and dry run
A few non-critical virtual machines or a copy of the customer data go through the real procedure. We measure how long each step takes and fix what the trial shows.
Weeks 4 and 5 — Waves
The rest moves in groups, each at an agreed time and each checked before the next begins. Old systems stay untouched so you can go back.
Week 6 — Cutover and handover
Billing is switched on the date you chose, DNS and customer notices are sent, and we hand over notes on how everything was done. Support for the move lasts until day 30.
Six weeks is a typical length for 30 working days, not a promise about any one project. The 30-working-day clock is the only commitment in the offer.

Risks and how we reduce them
A migration cannot promise zero downtime. These are the risks that matter and how each one is handled.
Cutover downtime
Moving a virtual machine means stopping it for some time. We test the procedure in the pilot to see how long it takes, and then agree a window per group of machines with you. We do not promise zero downtime.
Addresses and DNS
IP addresses and network settings can change when a machine moves. We list them in week 1, lower DNS TTLs before the cutover and tell your customers in advance.
Billing cut-over
The day billing moves is chosen with you. Both systems run side by side beforehand, and subscriptions at the old billing system are ended on the cutover day so nobody pays twice.
Guest software and licenses
Drivers change when a machine changes platform, and licenses of the software inside the machine can be tied to the old platform. We list both in the inventory so you can check them with the software vendors.
Rollback
The original systems are kept until you agree the move is finished, so every group has a way back.
